Check the tube chart. Some list several pairs.

The earlier chassis used a 6CJ3 and a 6HV5, heaters connected in series.
You had to use a GE or Zenith branded 6CJ3. There was a lot of Raytheon Japanese tubes designated 6CJ3/6DW4, that had a different heater current and wouldn't work in series with the 6HV5.
IIRC, the heater in the 6HV5 was receiving reduced heater voltage and wouldn't regulate properly.
